Abstract

In a dual bridge amplifier (1) for processing two input signals (Iin1; Iin2) and providing two amplified output signals (VL1; VL2) into two separate loads, comprising two signal amplifiers (10; 20) and one common buffer amplifier (30), the channel separation is improved by utilizing a feedback coupling over the load.
